5:1 since 100 cm is = to 1 meter
Answer:
The relationship shows a direct linear variation with a constant of variation of 1.
Step-by-step explanation:
This is true because the slope of the equation is 1
Answer:
We just add numerators and rewrite denominator.
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
Step-by-step explanation:
You mean unlike denominators and like denominators.
Adding like dominators: We just add numerators and rewrite denominator :
Example : 
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
For example :

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

Answer:
sometimes
Step-by-step explanation:
I know this is really late but the answer is y=-1/4x
